The Buy to let marketplace can be risky if you are inexperienced.
It's not wrong to go down this route however years of house price boom have left many thinking 'invest in property and you can't lose'.
Wrong! Property is fraught with risks and whilst house prices can rise they can also drop like a stone.
You should always keep the following situation in the back of your mind (we are not trying to ensure you do not sleep at night, rather simple providing the worst case scenario!):
You buy a house, no one rents it, and house prices crash. That is a dire situation, especially because of the gearing impact as explained above, which accelerates your loss.
Now that doesn't mean you shouldn't enter in to the buy to let market and rather just be aware of the risk - you are trading the potential to make substantial gains with the potential to make substantial loses.
Be careful about getting too "highly geared" (i.e. lots of mortgage and little actual cash invested) and only having property investments.
